2.6.2 CPX−FB38−specific process of start parameterisation during
switching on (system start)
Due to the CPX−FB38−specific limitations regarding para
meterisation (no parameterization by means of the higher−
level controller), start parameters can only be entered using
the handheld display (CPX−MMI) or Festo Maintenance Tool
(CPX−FMT).
The parameterisation during system start of the CPX terminal
istherefore
dependent on the setting of the system start
parameter stored in the bus node. This parameter establishes
whether the start parameterisation is loaded by the con
troller, the master or the FEC, or from the CPX bus node.
In the Festo Maintenance Tool, you will find the corresponding
setting under CPX" System settings", register System
parameters" System start": After the required start
parameters are set, choose the system start option Saved
parameters".
Process details can be found in Fig.2/9 and the following
explanations.
Substantial differences from the standard process:
No start parameterisation by means of the controller or
master, but possibly by means of the CPX−FEC controller
program (FEC in the remote controller operating mode).
Process with default parameter set" uses the factory−
programmed default parameter set (standard process
uses in this case the parameterisation from the field bus
control program).
Further information on parameterisation using CPX−FMT or
CPX−MMI can be found in the sections 2.5.4 and 2.5.5.
